Transjejunal biliary interventions: going back to a road less traveled.
Abstract Percutaneous transhepatic biliary interventions are not without risk and potential complications. In patients with bilioenteric anastomosis in whom repeat biliary interventions are expected, percutaneous transjejunal access is a very useful approach that is not frequently used nowadays. We provide a brief review of the history, indications, and current status of transjejunal biliary interventions. Transjejunal biliary access provides a relatively atraumatic pathway to the biliary system in patients that need repeat interventions. Multiple studies have provided convincing data that in appropriately chosen ...

Radiologic assessment and frequency of idiopathic osteosclerosis of jawbones: an interpopulation comparison.
Abstract BACKGROUND: Idiopathic osteosclerosis is a localized growth of compact bone with an unknown cause. This asymptomatic lesion is an insignificant finding and as such requires no treatment. It should be distinguished from other types of osteosclerosis created by inflammatory processes and systemic diseases. PURPOSE: To determine the prevalence and distribution of idiopathic osteosclerosis in the jawbones in Iran and to compare this prevalence and distribution with other populations. MATERIAL AND METHODS: This cross-sectional descriptive study was performed in the Dental School of Shahid Beheshti Un...

Histogram analysis of apparent diffusion coefficient map of diffusion-weighted MRI in endometrial cancer: a preliminary correlation study with histological grade.
CONCLUSION: Histogram analysis of ADC maps based on entire tumor volume can be useful for predicting the histological grade of endometrial cancer. The 90th and 95th percentiles of ADC were the most promising parameters for differentiating high from low grade. PMID: 24316663 [PubMed - as supplied by publisher] (Source: Acta Radiologica)

Venous sac embolization of pulmonary arteriovenous malformation: safety and effectiveness at mid-term follow-up.
This study included 15 consecutive patients (1 man, 14 women; mean age, 54 years; range, 22-76 years) with 50 PAVMs who underwent 26 procedures; four had a history of earlier cerebral infarction or exertional dyspnea. We first placed 0.018-inch interlocking detachable and/or 0.018-inch or 0.010-inch Guglielmi detachable coils to prevent systemic migration from the venous sac. We then packed the sac as tightly as possible and embolized the orifice at the proximal feeding artery. We used angiographic, clinical, and computed tomography (CT) studies to evaluate the treatment outcomes and safety of these procedures. The mean fo...

Adrenal adenoma and metastasis from clear cell renal cell carcinoma: can they be differentiated using standard MR techniques?
This study was institutional review board-approved; informed consent was waived. Eleven patients with 13 metastases and 13 patients with 15 adrenal adenomas in patients with clear cell RCC for evaluation of an adrenal mass underwent MR. Signal intensity on in- and opposed-phases, signal intensity index (SII), size, T2 SI, cystic change, necrosis, and hemorrhage were evaluated. Statistical analyses included Student t-test and Fisher exact test. If available, precontrast CT attenuation of the adrenal adenomas was measured. SII was correlated with attenuation using Pearson correlation coefficient. RESULTS: Mean size of a...

Latest developments in the imaging of fibrotic liver disease.
Abstract According to the World Health Organization, liver cirrhosis accounted for 1.8% of all deaths in Europe, causing about 170,000 deaths per year. Approximately 29 million persons in the EU suffer from chronic liver disease and this trend is on the rise. Liver disease is the EU's fifth most common cause of death accounting for at least one in six deaths. Early detection and monitoring of fibrosis has the potential to direct management of these chronic liver diseases and avert morbidity and mortality. Although the available techniques are in their infancy and the very early stages of fibrosis are difficult to ...

Magnetic resonance imaging of the immature skeleton.
Abstract Magnetic resonance (MR) is unique in its ability to allow assessment of bone marrow, epiphyseal, physeal, and articular cartilage as well as tendons and ligaments. An understanding of skeletal maturation and the accompanying changes on MR is of utmost importance in pediatric radiology. In particular, it is important to recognize the normal spectrum related to ossification and marrow transformation. This review will include a brief description of main indications and common pitfalls in musculoskeletal MR in children. Also, we will focus on the MR appearance of the growing pediatric skeleton on the most com...

Bone age assessment: automated techniques coming of age?
Abstract Bone age determination from hand radiographs is one of the oldest radiographic procedures. The first atlas was published by Poland in 1898, and to date the Greulich Pyle atlas, although it dates from 1959, is still the most commonly used method. Bone age rating is time-consuming, suffers from an unsatisfactorily high rater variability, and therefore already 25 years ago it was proposed to replace the manual rating by an automated, computerized method, a field nowadays referred to as computer-aided diagnosis (CAD). The pursuit of this goal reached a first stage of accomplishment in 1992-1996 with the prese...

The role of US in the evaluation of clinically suspected ulnar collateral ligament injuries of the thumb: spectrum of findings and differential diagnosis.
Abstract Injury to the ulnar collateral ligament (UCL) complex of the thumb is a common traumatic lesion that requires prompt imaging evaluation for adequate treatment. In this article, we review the role of ultrasound in diagnosis and illustrate the spectrum of both static and dynamic findings related to the UCL injuries. We also describe a number of alternative diagnoses in the vicinity of the first metacarpophalangeal joint that may present clinically as pseudoligamentous lesions in a trauma setting.
